使用带手柄的nodemailer发送动态电子邮件

Question

我遇到了一个问题，我似乎无法缩小我到底做错了什么。当我运行我的代码时，这是我得到的错误：

[Error: ENOENT: no such file or directory, open 'C:UsersAlexDesktopemailtestmain.handlebars'] { errno: -4058, code: 'ENOENT', syscall: 'open', path: 'C:\Users\Alex\Desktop\emailtest\main.handlebars' }

这是我的代码：

const nodemailer = require("nodemailer");
const hbs = require("nodemailer-express-handlebars");
const express = require("express");
const app = express();
const port = 3000;
const transporter = nodemailer.createTransport({
service: "gmail",
auth: {
user: "useremail",
pass: "userpassword",
},
//   tls: {
//     rejectUnauthorized: false,
//   },
});
transporter.use(
"compile",
hbs({
viewEngine: "express-handlebars",
viewPath: "views",
})
);
const mailOptions = {
from: "myemailhere",
to: "receiverpassword",
subject: "Automated Email",
template: "index",
};
transporter.sendMail(mailOptions, function (error, info) {
if (error) {
console.log(error);
} else {
console.log("Email sent: " + info.response);
}
});
app.listen(port, () => {
console.log(
`Listening at http://localhost:${port}`
);
});

文件夹结构：

server.js
views
-index.handlebars

在不使用Handlebars的情况下，我可以很好地发送电子邮件，但由于我需要一种动态填充HTML的方法，我认为如果我能让它发挥作用，Handlebars将是最好的选择。任何见解都将是伟大的，提前感谢！

const path = require('path');
const handlebarOptions = {
viewEngine: {
extName: ".handlebars",
partialsDir: path.resolve(__dirname, "views"),
defaultLayout: false,
},
viewPath: path.resolve(__dirname, "views"),
extName: ".handlebars",
};
trasnporter.use('compile', hbs(handlebarOptions));
